That's what I have... in operation... & I'm still having to increase those dose's weekly. Every time I test which is 1-2 times weekly, I use the BRS calculator, top up & increase the dose to accommodate what has been used in the previous 24 hrs. let it go usually 3-4 days check & it'll be low. So then I'll top it up & repeat, top it up & repeat. The reason I got a doser was so that I didn't have to try to maintain by means of testing so frequently..... I can't have a reactor on this setup. I've had this online since Jan. & the daily amounts have been increased every single week with the exception of one. If that's set it & forget it, then I must be missing something because I've yet to achieve & maintain levels yet. My corals are growing & thirsty?? but this is high maintenance.

What salt are you using? What are the numbers? You may be trying to make up for the lack of Ca in your salt. Or, you could just have a high demand, like me, in your tank and that's the way it is.

Again I test & match the in-going water to existing. Yes I agree high demand but can't help but wonder will it settle out for a while? Ultimately I guess I'm looking for people who've had a similar experience while trying to "dial in" their SA doser.


Why is sps so awesome that I had to fill my 1st tank with them, & then turn out to have this & patience as my biggest issue's so far?
